Specification of Letters Patent.

Application filed Becember 18, 1916.

To aZZ whom it may concern:

Be it known that I, EDWARD E. Ennrorr, a citizen of the United States, residing at Indianapolis, Marion county, and State of Serial No. 13?,672.

are carried the garments to be dried after they have been cleaned with gasolcne.

In the lower part of one of the side walls of the drying room and preferably directly 5 Indiana, have invented and discovered ceropposite the hot air inlet, there is provided tain new and useful improvements in Appaan exit opening 8 adapted to permit the esratus for Drying Gasolene Cleaned Garcape of the fumes of gasolene. This opening ments, of which the following is a specificacommunicates with a flue pipe 9 extending tion. vertically along one side of the drying room 10 My invention relates to apparatus for dryand at its top this fine may be provided, if ing gasolene cleaned garments'and its obdesired, with a removable hood 10. The jects are to provide a construction whereby connection between the dryingroom and the the safe and comparatively rapid drying of flue 9 .is preferably provided by means of garments that have been cleaned with gasoa laterally extended and funnel shaped. body 15 lene may be carried out economically and 11 which provides a comparatively large '70 effectively. area for the connecting joint between the My invention employs and applies to so chamber and the flue, therebyobtaininpg a called cleaning methods the principles of a free escape of the gasolene vapors. natural draft of the dryingair created by In order to increase the heat units within 0 heat movement and of the descending: vapors h drying r om the flue pipe 12 leading and fumes heavier than air. To these ends from the upper part of the furnace is prefmy invention is embodied in the method r ly led through the drying room and hereinafter described and in the apparatus emerges in an exterior extension 13 above herein set forth and illustrated in the accomthe latter. This pipe conveys the gaseous 25 panving drawings. products of combustion from the furnace Th figure show in th acc a yi g and through the closed pipe leading through drawing" is a vertical sectional view through he drying room to the. atmosphere. the drying room, 'ith the heater in partial Hung by means of a suitable support section. mounted in the side wall of the drying room 3 Referring to the drawings, 1 is a heater which the inlet pipe enters and. directly or furnace which may be supplied with gas, above the inlet is a flexible valve 14 prefercharcoal or coal as the fuel. A gas heater is ably formed of a piece of thin textile mateherein shown. From the air chamber of this rial and which is adapted to depend freely furnace leads a hot air supply pipe 2, in front of the inlet and the function of 35 through a partition 3 which constitutes a which is to permit the hot air from the inlet preferable although not an essential part of to pass freely into the drying room but the arrangement and which serves to sepawhich upon the creation'of a pressure in the rate the compartment in which the furnace drying room greater than the pressure of is located from that containing the dry the incoming air will be forced back against 40 room. The hot air supply pipe leads into the wall over the opening, so as to close the 9 the lower part of a dry room 4. This dry inlet and prevent the backing up of the room consists of a cabinet preferably made gasolene vap rs into the hot air supply pipe. of sheet metal and entirely inclosed except The apparatus above described provides for the gas inlet and exit openings and a means whereby what may be characterized 45 door 5 mounted in the front thereof. The as a quiescent or natural draft method of cabinet is of a size that makes it capable of drying gasolene cleaned garments is probeing readily transported and set up in any vided. The furnace heats the air admitted desired location within a building. It is thereto and such heated air will rise and preferably about 10 feet in height by four pass out from the air chamber into the hot 50 feet wide by four feet deep, although, of air supply pipe 2, owing to its tendency to course, these dimensions may be varied as rise and will be drawn into the drying room desired. The drying room is preferably promerely by the natural draft. The pressure vided with a false bottom 6 and at its upper of this air due to its heat will be sufficientto end near the top is provided with a cross blow the flexible valve away from the open- 5 rod 7 adapted to receive hangers on which ing and permit the air to enter the chamber where it will rise into contact with the garments hung on the supporting cross rod at the top of the garments. The gasolene vapors and fumes being heavier than air, will descend and since the top of the chamber is closed and the side walls are also closed except for the inlet and exit openings, such cleaned garments, in combination with afurnace, a closed drying room cabinet, a hot air supply pipe leading from the hot air chamber of the furnace to the lower part of the drying room to convey the heated air by natural draft alone, means leading from the lower partof the cabinet for drawing 0E the gasolene vapors by natural draft alone, means for supporting garments in the upper part of said cabinet, closed means for conveying gaseous products of combustionfrom the furnace through the cabinet, said outlet means for the gasolene vapors and the outlet means for the gaseous products of c0mbustiOn being separated and leading to different points of distribution of the gases and vaors. p 2. In combination with a closed drying room cabinet, a hot a1r supply furnace having communication with the drying room feeding the air thereto solely by the expansive pressure of the hot air thereof, and vapor exit means for the cabinet located only at the bottom of the room and opposite the hot air inlet, a flue leading from said exit and an automatic valve adapted to control the inlet opening and prevent the flow of vapors from the room into the air supply pipe by back pressurein the drying room.

3. In combination With a furnace, a hot air supply pipe leading from said furnace, a closed drying room cabinet to which said pipe leads to convey air under the expansive force due to its heat, a flexible freely hung I with the cabinet at the lower part of the latter, a vapor escape fiue leading from said cabinet outlet, and a smoke pipe leading from the furnace through the cabinet.

In witness whereof, I have hereunto set my hand and seal at-Indianapolis, Marion county, Indiana, this 16th day of December, A. D. nineteen hundred and sixteen.
